This directory contains precompiled Linux kernels.  Brief descriptions of
each kernel is given below.  You can find complete descriptions of the
kernels in the individual "config" files in each kernel subdirectory.
You may find it helpful to "diff" the configs to find out how they vary.

   javastation.n  Sun JavaStation "Mr. Coffee" and "Krups"  support.  There are
                   no IDE or SCSI drivers in this kernel, as the Javastation has
                   no provisions for those.  This kernel is also set up
                   with proper network booting and root filesystem support.
                   Systems that should use this image:

                      Sun JavaStations 
                      Sun Xterminal 1 (depending on needs)

   sun4.s         Not available -  Sun 4 systems are no longer supported.
                   If enough intrest is expressed and testing is either
                   provided or equipment given/loaned, this may come back
                   in the future.

   sun4cdm.s      Support for the sun4c family of SPARC systems. 
                   Contains SCSI disk and CD-ROM support and all available
                   SPARC SCSI drivers.  NOTE:  This kernel can also boot
                   sun4m and sun4d machines, but does not support SMP
                   machines in those families.

                      Sun4c machines:
                      Sun SPARCstation SLC
                      Sun SPARCstation ELC
                      Sun SPARCstation IPC
                      Sun SPARCstation IPX
                      Sun SPARCstation/server 1
                      Sun SPARCstation/server 1+
                      Sun SPARCstation/server 2

                      Sun4d machines:
                      Sun SPARCserver 1000, 1000E
                      Sun SPARCcenter 2000, 2000E

                      Sun4m machines:
                      Sun SPARCclassic
                      Sun SPARCstation LC
                      Sun SPARCstation LX
                      Sun SPARCstation 4
                      Sun SPARCstation/server 5
                      Sun SPARCstation/server 10
                      Sun SPARCstation/server 20
                      Sun Xterminal 1 (depending on needs)

   sun4dm_smp.s   Support for the multiprocessing capabilities of the sun4d
                   and sun4m families of SPARC systems.  Contains SCSI disk
                   and CD-ROM support and all available SPARC SCSI drivers. 

                  SUN4D NOTICE:  EXPERIMENTAL.  Use this kernel ONLY if
                   you want to help fix the kernel bugs with this processor
                   type.  SMP on these machines is UNSTABLE.

These kernels are offered for installation during the setup program and they
are provided here as a reference for those wanting to rebuild their kernel.

These kernels are also perfectly fine to add to your system.  Installation
is easy.  Suppose you want to install the sun4u.s kernel.  First pick a
kernel version - 2.4.31 - then have a look at what's in that directory.

  Say it contains these items:

   modules.tar.gz
   System.map
   config
   vmlinux

The "modules" archive contains kernel modules specific to the sun4u.s
kernel.  Decompress the contents to /lib/modules/2.4.31.
If you previously had a /lib/modules/2.4.31 directory, make sure it's empty
before copying over the new one.

   rm -rf /lib/modules/2.4.31
   mkdir /lib/modules/2.4.31
   cd /
   tar -zxvf $PATH_TO_MODULES/modules.tar.gz

The "System.map" and "config" file should be placed in /boot for reference
purposes.  The System.map file is useful for kernel developers and the config
file is the kernel configuration file used to build the kernel.  If
you decide to recompile your kernel, you may wish to start with this config
as a default.  Having it in /boot makes a nice reference.

   cp -a System.map config /boot

The last file is the actual kernel.  Depending on your partitioning strategy, 
you may be able to copy it to / and reboot.  You should double-check
your /etc/silo.conf to make sure all the paths are correct.

   cp -a vmlinux /vmlinux

That's it.  Be careful not to install a kernel that will render the system
unbootable.
